METHOD FOR TRANSMITTING DATA IN COMMUNICATION SYSTEM INCLUDING AT LEAST ONE TRANSMITTER AND ONE RECEIVER, COMMUNICATION SYSTEM INCLUDING AT LEAST ONE TRANSMITTER AND ONE RECEIVER, AND DEVICE CONFIGURED SO AS TO TRANSMIT AND RECEIVE SIGNAL FORMED BY AT LEAST ONE SEQUENCE COMPOSED OF Ns PULSES OVER Ns TIME WINDOWS

摘要

PROBLEM TO BE SOLVED: To provide a modulation/demodulation system with which a receiver can reproduce information carried by a pulse sequence in a receiver end, without requiring accurate positioning of a received pulse sequence in terms of time.

SOLUTION: The method includes at least one symbol decoding step in the course of which at least one modulation value Pwk representative of an amount of power carried by each pulse sequence Tsgk is computed and compared to at least one predetermined threshold value Thvk. The Thvk will be computed beforehand by equating first and second probability density functions representing a likelihood for the transmitted signal to carry a first symbol and a likelihood for the transmitted signal to carry a second symbol, respectively. The method enables to limit the processing time and power needed for performing the demodulation of a power-modulated UWB signal.
